Fossil sulphate-reducing bacteria in the Bleiberg lead-zinc deposit, Austria
Springer Science and Business Media LLC - Tập 40 - Trang 123-126 - 2005
Henryk Kucha, Erich Schroll, Eugen F. Stumpfl
Polished ore samples from the world-class Bleiberg lead-zinc deposit in Austria were studied by Field Emission Scanning Electron Microscopy (FESEM) at magnifications in the range of 105–106. The zinc ore shows nano-sized sphalerite filaments and spherules which are morphologically similar to recent biofilms of sulphate-reducing bacteria. The activity of sulphate-reducing bacteria is suggested by a...... hiện toàn bộ
Paleomagnetism of the Cu–Zn–Pb-bearing Kupferschiefer black shale (Upper Permian) at Sangerhausen, Germany
Springer Science and Business Media LLC - Tập 46 - Trang 137-152 - 2010
David T. A. Symons, Kazuo Kawasaki, Sabine Walther, Gregor Borg
Syngenetic, diagenetic and epigenetic models have been proposed for the Cu–Zn–Pb Kupferschiefer mineralization at Sangerhausen, Germany. Paleomagnetic and rock magnetic measurements have been made on 205 specimens from mine workings on the margin of the Sangerhausen Syncline. The mineralization is richest in the ∼0.5-m-thick Upper Permian (258 ± 2 Ma) Kupferschiefer black marly shale (nine sites) ...... hiện toàn bộ
European Phanerozoic metallogenesis
Springer Science and Business Media LLC - Tập 34 - Trang 417-421 - 1999
D. Rickard
Phanerozoic metallogenesis in Europe displays divergent characteristics which may be related to the variable nature of the three great European Phanerozoic orogens: Caledonian, Variscan and Alpine. These reflect different geodynamic processes. The Caledonian orogen resulted from the interaction of essentially oceanic with continental lithosphere, whilst the Variscan and Alpine orogens evolved mai...... hiện toàn bộ

Das Cu-W-S-System und seine Mineralien sowie ein neues Tungstenitvorkommen in Kipushi/Katanga
Springer Science and Business Media LLC - Tập 8 - Trang 291-300 - 1973
G. H. Moh
Die Phasenbeziehungen im Cu-W-S-System wurden zwischen 900 °C und Zimmertemperatur durch DTA- und Abschreckungsexperimente in Quarzglas-und in unter Druck kollabierenden Goldampullen, sowie durch eine Reihe von Verwitterungsversuchen und Umsetzungen in wässrigen Lösungen untersucht. Die im System auftretenden Verbindungen sind Cu2S (Kupferglanz), Cu1.97S (Djurleit), Cu1.75S (Anilit), Cu1+xS (blaub...... hiện toàn bộ

A trace metal, stable isotope (H, O, S), and geochronological (U-Pb titanite) characterization of hybridized gold orebodies in the Missanabie-Renabie district, Wawa subprovince (Canada)
Springer Science and Business Media LLC - Tập 56 - Trang 561-582 - 2020
Jordan A. McDivitt, Daniel J. Kontak, Bruno Lafrance, Joseph A. Petrus, Mostafa Fayek
Mineralized shear zones in the Archean Missanabie-Renabie gold district (~ 1.1 Moz Au; Wawa, Ontario, Canada) locally define composite orebodies that record three hydrothermal events: (1) a pre-orogenic Au1 event (pre-D1 and pre-prograde-metamorphic); (2) a syn-orogenic, post-peak-metamorphic Retrograde event (syn-D3); and (3) a late syn-to post-orogenic Au2 event (late syn- to post-D4).

Regionally metamorphosed greisens at Cetoraz, the Bohemian-Moravian Heights (Českomoravská vrchovina), Czechoslovakia
Springer Science and Business Media LLC - Tập 11 - Trang 210-217 - 1976
D. Němec, I. Tenčík
Investigation of the greisen occurrence at Cetoraz, Bohemian-Moravian Heights, which underwent a regional metamorphism, has shown that the main greisen assemblages are stable under the conditions of regional metamorphism, as long as they do not attain the sillimanite-almandine-orthoclase subfacies, when muscovite disappears. The ore minerals are also stable. In the mineralogy of the greisens, the ...... hiện toàn bộ
Stable isotope and fluid inclusion study of sediment-hosted stratiform copper deposits from the Neuquén Basin, Argentina
Springer Science and Business Media LLC - - 2018
Ana Laura Rainoldi, Marta B. Franchini, Adrian J. Boyce, Adolfo Giusiano, Nora N. Cesaretti, Josefina Pons, Francisco J. Ríos
The Los Chihuidos and El Porvenir deposits of the Neuquén Basin are examples of sediment-hosted stratiform Cu deposits generated by interaction of hydrocarbons and formation water with host red beds and metal-charged basinal brines. During early diagenesis of red beds precipitated hematite, kaolinite at 60 °C from meteoric water followed by calcite 1 (δ13C − 8 to − 3.3‰) and barite (δ34S + 4.1‰) w...... hiện toàn bộ
